Armed forces were no longer primarily feudal levies serving under a vassal's obligation who went home after forty days; they were recruited bodies who served for pay.
The transition of armed forces from feudal systems to paid military bodies marked a significant shift in the dynamics of warfare. Previously, armies were composed of vassals who served under feudal obligations, often returning home after a short period, typically around forty days. This system relied on the loyalty and duty of nobles, which limited military engagement and effectiveness.
However, as the nature of warfare evolved, these forces transformed into professional armies that were recruited and compensated financially. This change allowed for greater commitment and longer service durations, leading to a more reliable and effective military establishment. Barbara W. Tuchman highlights this pivotal moment as a turning point in military history during the tumultuous 14th century.
